Photonics-based radar with a photonic de-chirp receiver has the advantages of broadband operation and real-time signal processing, but it suffers from interference from image frequencies and other undesired frequency-mixing components, due to single-channel real-valued photonic frequency mixing. In this paper, we propose a photonics-based radar with a photonic frequency-doubling transmitter and a balanced in-phase and quadrature (I/Q) de-chirp receiver. This radar transmits broadband linearly fr

Single-nanowire solar cells with a unique light-concentration property are expected to exceed the Shockley–Queisser limit. The architecture of single nanowire is an important factor to regulate its optical performance. We designed a trilobal silicon nanowire (SiNW) with two equivalent scales that possesses superior light-absorption efficiency in the whole wavelength range and shows good tolerance for incident angle. The electric field distribution in this geometry is concentrated in the blade wi

为了从高分辨率遥感影像中高精度的提取各种工业固体废物,提出了基于支持向量机(SVM)的工业固体废物特征快速提取算法,首先对遥感影像进行各向异性扩散滤波,然后针对高分辨率遥感影像信息量丰富和工业固体废物堆复杂度高的特点,提出基于1-v-1的SVM的多种工业固体废物的多分类策略,在提高精度的同时,兼顾了工业固体废物特征识别的效率。研究结果表明:SVM对工业固体废物判别能力比常规方法有更强的优势,从遥感影像中不仅能准确地辨别出工业固体废物堆的线形特征,还能识别出其材质和类型;该算法能同时识别出多种工业固体废物,执行效率更高。

This paper proposes a new method to weight subspaces in feature groups and individual features for clustering high-dimensional data. In this method, the features of high-dimensional data are divided into feature groups, based on their natural characteristics. Two types of weights are introduced to the clustering process to simultaneously identify the importance of feature groups and individual features in each cluster. A new optimization model is given to define the optimization process and a ne

This paper presents a Crotch Ensemble classification model for high dimensional data. A Crotch Ensemble is obtained from a decision cluster tree built by calling a clustering algorithm recursively. A crotch is an inner node of the tree together with its direct children. If the children of a crotch h
